ADVERTI S ING APPARATUS Filed Aug. 17, 1928 2 Sheets-Sheet 2 Inventor Patented Apr. 1, 1930 UNITED STATES PATENT OFFICE JAMES C. MITCHELL, OF JOPLIN, MISSOURI, ASSIGNOR TO 0. E. RUSSELL, OF JOYLIN, MISSOURI ADVERTISING AP PA R-JA TUS' Application filed August 17, 1928.

The object of my said invention is the provision of a simple, inexpensive, and durable apparatus, comprising a rotary member, adapted to bear a large number of advertisements in proportion to its size, and means whereby currents of air are utilized for the turning of the said member about its axis, so that all of the advertisements on the member may be viewed by persons located at different viewpoints.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming a partof this specification:

Figure 1 is a side elevation of the preferred embodiment of my invention.

Figure 2 is atop plan view of the same.

Figure 3 is an enlarged view of the upper portion of the apparatus, said view being partly in section and partly in elevation.

Figure 4 is a horizontal section taken in a. plane immediately below the top disc of the rotary member looking downwardly.

Similar numerals of reference designate corresponding parts in all of the views of the drawings. Among other elements, my improvement comprises a standard 1. This standard may be and preferably is formed of concrete, and is designed to be supported by the ground or any other appropriate supporting means and to rise therefrom. Said member or standard 1 is fixed, and when deemed expedient it may be appropriately fixed in the ground or to an appropriate platform on which it is mounted.

Fixed to and rising from the center of the upper end of the standard 1 is a pivot post 2, as seen in Figures 8 and 4. It will be also noted, from a comparison of Figures 3 and 4, that the standard 1 is provided with a circular series of vertically disposed wheels or anti-friction bearings 3, the same being located about the post 2.

The rotary member of my improvement is designated by 4. It is cylindrical in form and is preferably, though not necessarlly formed of sheet metal. On its outer side, the member 4 is designed to bear a plurality of advertisements as indicated by the legend Serial No. 300,317.

in Figure 1, though manifestly when it is desired, a single advertisement may be placed on the outside of the member 4, throughout the area thereof. Said member 4 is open, at its lower end and is provided at its upper end with a closure disc 5, and it will also be noted that the member 4 is provided, at itsouter end with an annular toothed flange 6, for a. purpose to be presently described. The, member 4 is mounted onthe pivot post 2 and is supported by the wheels or other appropriate anti-friction devices 3 and is, designed to be turned, about the post 2,,so that all. of the advertisement or advertisements on the member 4' may be seen to advantageby aperson at a p articular viewpoint.

- For the purpose of preventing lateral deflection of the member 4, incident to rotation thereof, and also in order tomaintain the member 4in an upright positiointhe standard 1 is equipped, near. the lower end of the memher 4 with wheels 7, which, by bearing against the innerside o f;the member 4;, are adapted to perform the functionsindicated.

Supported in part by and turnable about the post 2 is a tubular member 8 having a dome 9 to receive the upper, preferably tapered end of the post 2, and also having kerfs 10, the latter to enable the tubular member 8 to clear the flange 6-, as will be apparent from Figures 1 and 3. At one end, the tubular member 8 is provided with a vane 11, and in the opposite end portion of the member 8 is journaled a shaft 12 which carries a wind wheel 13 and a small spur gear 14. The latter intermeshes with the teeth of the flange 6, as will be readily understood from Figure 3.

In the practical use of my improvement, it will be understood that wind acting against the wheel 13 will turn the shaft 12, and the spur gear 14, and the spur gear 14 through the medium of its teeth, meshed with the teeth of the flange 6 will turn the cylindrical member 4 about its axis for the purpose before indicated.

It will also be appreciated from the foregoing that because of the comparatively small diameter of the spur gear 14, the member 4 will be rotated at a low rate of speed, notwithstanding the wind wheel 13, may be driven at a comparatively high rate of speed.

My novel apparatus is designed more especially for use in the open air, and in this connection, it will be noted that the apparatus as a whole, is well adapted to withstand exposure to the elements.

I have specifically described the preferred embodiment of my invention, in order to impart a full, clear and exact understanding of the same. I do not desire, however, to be understood as limiting myself to the precise construotion illustrated and described, my invention being described by my appended claim, within the scope of which modifications may be made, Without departure from my inventiou.

I claim:

An advertising apparatus comprising a support, a hollow rotary member mounted on 1nd turnable about the support and having a flange of annular form at its upper end, means on the support and bearing against the inner side of the hollow rotary member to prevent deflection of the latter, a pivot post carried by the support and extending upwardly through the rotary member, a diametrically disposed member arranged above the rotary member and supported by and turnable about said post, and having a vane at one end and also having kerfs enabling it to clear the flange of the rotary memher, a shaft journaled in the opposite end portion of said diametrically disposed memher and extending from said member, a Windwheel fixed to said shaft, and a Wheel also fixed to the shaft and engaging with the flange of the rotary member.

In testimony whereof I affix my signature.

JAMES C. MITCHELL.
